Abstract: A shaft sealing ring for sealing shafts, running very quickly and, if appropriate, in an eccentric manner, for loaders of internal combustion engines, in particular driven mechanically, consists solidly of polytetrafluoroethylene, the axial limb forming the adhesion part on the outside circumference and the radial limb forming the sealing lip on the inside circumference being machined from a polytetrafluoroethylene blank. Due to its solid production from polytetrafluoroethylene, the ring can be used even in very rapidly and eccentrically running shafts with a long service life without the formation of cracks and ruptures in the radial limb; due to the lack of a metallic housing ring, it has a smaller radial and axial construction space and can be manufactured economically at low expense. <IMAGE>

IPC: H04N3/18
Filed: 1989-10-26
Abstract: An input signal (from 100) at a horizontal frequency is coupled to a deflection circuit (99) through an isolation transformer (T3) during a power-on operation but not during a power-off operation. A voltage (V LIN ) at a horizontal deflection frequency is developed in a linearity inductor (L LIN ) of the deflection circuit. The voltage in the linearity inductor is rectified to produce a rectified signal (V₁₂₁) that is coupled to an input terminal (110a) of a regulator oscillator (110) of a power supply. The rectified signal (V₁₂₁) is coupled to the regulator oscillator (110) in an electrically nonisolated manner with respect to electrical shock hazard isolation, and is electrically isolated by the transformer (T3) from the input signal (from 100). The regulator oscillator (110) generates trigger pulses (S c ) for controlling the switching operation of an SCR switch (200) of the power supply to produce an output supply voltage (B+) that energizes the deflection circuit (99). The regulator oscillator (110) is energized during both power-up and power-off operation and is responsive to the rectified signal (V₁₂₁) to cause the frequency of the trigger pulses (S c ) of the oscillator (110) to increase during power-off operation. The increased frequency causes the anode-to-cathode voltage of the SCR switch (200) to be small enough to prevent latching of the SCR switch during the power-off operation. By preventing SCR switch latching, audible parasitic vibrations in the power supply are avoided.

Abstract: The method involves directing first (B1) and second (B2) separate illuminating beams towards a photosensitive film (HP) from separate fixed apparent beam source positions (S1 and S2) respectively in such a manner that the beams are caused to overlap at the point of incidence at the photosensitive film (HP). Stationary interference fringes are generated and the beams are caused to scan in a raster type pattern over the photosensitive film in such a manner whereby overlapping of the beams (B1 and B2) is maintained throughout the exposure of the film. The apparatus in one embodiment involves the generation of a third illuminating beam (B3) which is used to control means (SC2) to control an associated scanner to effect synchronised movement of the second beam (B2) with the first beam (B1). A further embodiment involves memorising the scanning movement of beam (B1) in a memory (CM) and using the memorised scanning pattern to control the scanner (S2) to maintain beam overlap.

Abstract: In an automatic cut-out, the switch link (5), the latch (6) and the latch abutment (7) are combined to form an assembly which can be pivoted about a bearing journal (4) provided in the housing (1). The latch (6) is stressed by a spring (8) and can be pivoted with respect to the latch abutment (7) which, for its part, is supported such that it can pivot on the switch link (5). This assembly is coupled by a thrust guide (25), which engages in a mouth (9) between the latch (6) and the latch abutment (7), to an operating head (20). As a result of pivoting the latch (6) under the influence of the plunger (54) of the magnetic trip device (51) or of the tension lever (67) under the influence of the bimetallic strip (41), the mouth (9) is opened such that the end (26), which is held in it, of the thrust guide (25) is released. In consequence, the switch link (5) can be pivoted by the tension spring (16) into the off position. The bimetallic strip (41) is mounted on a support (42) which is fixed in the housing (1) via conical journals (45) which engage in holes (44) in the support (42). In the off position, the switch link (5) rests on the support (42) for the bimetallic strip (41). <IMAGE>
